COLLAPSIBLE BOAT.

Application ined august 1o, 1922. serial No. 580,981.

i To all whom t may concern:

An object of my invention is toprovide a i collapsible boat, that may be easily collapsed,

in such a manner, that it may be carried around with very little difficulty.

A further object of my invention is to provide a collapsible boat, that is constructed with a frame made from coiled springs so that the boat will` suife'r no damage, if it is accidentally bumped against any obstruction, such as a rock. Y

A still further object of my invention is to provide aV collapsible boat, that is pro-- vided with a keel that is pivote :l at its ends, that may be used to stabilize the boat in vrough water.

A still further object of my invention `is to provide a collapsible boat,that has` removable seats. g

A still further object of my invention is to provide a collapsibleiboat, that is provided with folding rib members, which may be swung up to adapt a cover to be mounted thereon, to absolutely guard against the sinking of the boat in very rough water.

A still further objectv of my invention is to provide a collapsible boat, that is strong, durable, simple and inexpensive in construction, and that is well adapted to be used for the purpose for which it is designed.

Other obiects and advantages of the invention will become apparent during the course of the following description.

In the drawings, wherein like numerals are employed to designate like parts throughout the same,

Figure l is a topv plan view of my boat with the cover removed,

Figure 2 is a longitudinal section of my boat, showing the cover in place,

Figure 3 is a detailed section illustrating the means whereby the cover is secured to body of the boat,

Figure 4 is a transverse section taken through my boat, illustrating one of the circular ribs in elevation, andV Figure 5 is a detail of the circular ribs lapsed for transportation.

used in my invention, and the means whereby they may be swung around in such a position that the boat may easily be collapsed.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention the numeral 1() designates the keel which is carried at its end by means of the members 11 which are the ends of the curved springs` 12, said coiled springs 12 being the frame of my boat. The coiled springs are clearly shown in Figure l of the drawings, and it will be seen that they are secured at their ends by means of the blocks 13. A canvas or other like material body 14 is secured in any suitable manner to the coiled springs 12., y

The numeral 15 designates a U-shaped strip of material, that is bent to conform with the base of the keellO, as is clearly shown in Figure 2 of the drawings. The circular ribs 16, which are hinged at their center by means of a hinge 17 are mounted on the U-shaped strip of material 15 in any suitable manner. The circular ribs may be mounted by means of the clips 18 as are illustrated in Figure 2, or may be connected as is clearly shown in Figure 5 lof the draw ings, so that the ribs may be turned around, in order that the boat may easily be col- Normally the circular ribs are bent down, that is the upper half is swung down so that the ribs will represent a U, but they may readily be swung upwardly into a position as is clearly shown in Figure 2, in order that a top covering 19 may be used. The covering 9 ordinarily is not in use, and may be rolled up and carried in any convenient manner within the boat, but when it is desired to use the covering during a storm or the like, the cov ering may be mounted over the circular ribs 16 and fastened to the coiled spring members in any suitable manner.

As stated above, the keel 10 is carried by the ends of the coil springs 12 and it is adapted to be swung to the right and left as it is desired, in rough water to facilitate in stabilizing the boat. Normally the keel 10 should be in a position as is shown in Figure 4 of the drawings, and I have devised means whereby the keel may be carried in such a position and which may be readily freed to cover upon the ends 11. In accomplishing this end, I provide a plurality of threaded sleeves 2O which are mounted in the bottom of the boat, being extended through the strip 15 and the canvas body 14,. The` keel is provided with threaded recesses 2l which are adapted to be registered With the threaded openings in the sleeves 20. It will thus be seen that a threaded bolt 22 screwed to the sleeves 20 and into the recess 2l in the keel 10, will hold the keel in thedesired position. It will further be noted that the internally threaded sleeve 2O and the threaded bolt 22 will form an absolutely Water-tight connection. VVh-en it is desired that the keel l0 be allowed to swing freely, the bolt 22 is partially removed, that is entirely removed from the recess Within the keel 10 but not from the sleeve 20. It will thus be seen that the bolt 22 will Vact as a. plug when the keel is not in the position as isshovvn in Figure l, but is allowed to swing to the right or left, and at all times a Watertight connection is had. It will readily be seen that the keel 10 can be made rigid by swinging the same down and screwing the bolt 22 back into the recess 2l in the keel l0. Any form of seat or seats 23 may be mounted on the coiled springs 12 by suitable clips 24, and may readily be removed when it is desired to'collapse the boat.

It vvill thus be seen that I have devised collapsible boat, that is entirely diilerent from any of the boats now in use, and I Wish to call particular attention to the coiled springs 1 2, and the pivoted keel l0. It will be seen that by means of the coiled springs `l2, that by striking a rock or the like, no damage Will occur, either in drying the boat or braking the same, as is very commonly done in the ordinary row boat or canoes that are nouT in'use. Y

v It is to be understood that the form of my invention herewith shown and described, is

f to be taken as a,preferredembodin'ient of the same, and that various changes in the shape, size'v and arrangementy of parts may be resorted to, without departing from the spirit of ymy invention or the scope ot' the sub,- joined claims. l

Having thus described my invention, I

vGleim i l. Aboat of the class described comprising a resilient frame, a Water-proof body secured thereto, a keel pivoted tothe end or' said frame, a plurality of oldable annular ribs, adapted to be rotated, said boat being adapted to be collapsed. f

e. A boat ol the class described comprising gunvvales Jformed of substantially longitudinal coil springs, a Water-proof body secured thereto, toldable annular ribs mounted in said body, and a keel pivoted to the end of the gunwvales.

5. A boat of the class; described comprisy ing gunwales formed Jfrom substantially'longitudinal coil springs, a Water-proof body secured thereto, a U-shaped bar mounted transversely Within the body, a plurality of t'oldable annular ribs carried by the U- shaped bar, a keel pivoted tothe end of said gunwales `and means to hold said keel stationary.

6. A boat of the class described comprising gunwales 'formed from substantially longitudinal coil springs, each ot said gun- Wales being formed' from a `continuous spring, a Water-proof body secured thereto, a U-shaped bar mounted transversely within the body, a plurality of foldable annular ribs carried the U-shaped bar, and adapted to be rotated, a keel pivoted to the ends or' said gunvvales, an internally threaded recess formed in the upper side or' said keel, and a screw threaded plug carried byv saidU-sha-pedbar adapted to be received Within said recess.

In testimonywhereof I aix my signature.
